Authorities say investigators are pursuing more than 90 leads in the mysterious death of a South Dakota woman who was shot in her car along an interstate in Missouri with her two children in the backseat.

Nearly three weeks after Melissa Peskey was killed on a rural stretch of I-70 near Boonville, the Missouri State Highway Patrol continues to investigate, but has publicly provided few details about the death of the Hartford real estate agent.

The Argus Leader reports Sgt. Scott White won't say whether the children, ages 5 and 11, have provided any clues about their mother's death. Authorities have not disclosed whether the vehicle was in motion at the time of the shooting, what type of weapon was involved or whether Peskey may have been targeted.

Authorities continue to solicit leads on social media.
